Security incident report: the facts to record before anyone investigates

A security incident report records a suspected event, such as a phishing email, a lost device or an account that signed in from an unexpected place, along with what the reporter saw and did. It should capture facts in order and the time they were first noticed, without copying a password or the sensitive data itself. The security lead decides what happens next, and the report is the starting record for that decision.

Field blueprint

What the security lead needs in the first report

FieldTypeRequiredWhy you ask it

Reporter name

Short textRequired

Lets the security lead ask for detail and confirm who first saw the event.

Reporter work email

EmailRequired

The main route for follow-up. It should be an address you can read while the incident is open.

Reporter phone

PhoneOptional

Lets the security lead call you when email is too slow for the question in hand.

Kind of event

Suspicious email or phishingLost or stolen deviceSuspected account compromiseAccess to data you should not seeMalware or ransomware warningData sent to the wrong personOther suspected security event
DropdownRequired

Tells the security lead which kind of event the report covers.

Date first noticed

DateRequired

Starts the timeline. Estimate if you are not sure, and say so in the description.

Time first noticed, with time zone

Short textOptional

Narrows the timeline when more than one event happened on the same day.

Systems, devices or accounts involved

Do not include passwords, codes or recovery answers.

Long textRequired

Names what the security team must check. Use names and identifiers, never the secret itself.

What you saw

For example: a message asked me to confirm my login on a page that was not our sign-in site.

Long textRequired

Records observable facts, such as a message, a sign-in prompt or a missing file, rather than your conclusion.

Actions taken so far

Long textOptional

Shows what has already changed, such as a password reset or a disconnected device, so the team does not repeat or undo it.

Could personal, customer or financial data be involved?

YesNoNot sure
Single choiceRequired

Tells the privacy or security lead whether a data review is needed. Answer without copying the data itself.

Is anyone else affected right now?

Yes, others may be affectedNo, only my account or deviceNot sure
Single choiceRequired

Shows whether the event is spreading or still contained.

Evidence you keep

The form cannot hold the original email or log, so tell the security team where it is kept.

Section header

Separates the facts you describe from material that stays where it is.

Mistakes to avoid

Four things that slow down a security report

Asking the reporter to investigate

A report that asks staff to check logs or run a scan sends them into work they are not trained for, and it can disturb evidence. Keep the form to what they saw and did.

Collecting the secret itself

If the form asks for the password that may have leaked, you have created a second copy of it. Ask for the account name and the time of the change instead.

Waiting for certainty before reporting

Early reports are more useful than perfect ones. Tell staff to report a suspicion and say they are not sure, rather than waiting until they are certain.

Expecting the report to close the incident

A report does not contain the incident. The security lead decides containment, and any notice to customers or regulators follows the process your organization has set up for that.

After a response arrives

How the report moves after it is submitted

  1. The creator is notified after the schedule runs

    Attain OS stores the report, and a scheduled job processes it hourly in production. The creator is notified after that processing, so also message the security lead directly through your own channel.

  2. Do not wait for the grid to start containment

    If an account is still signed in under someone else's control, the security lead acts from the source system. The grid is the record of the report, not the response to it.

  3. Name an owner for each report

    When Customer Care case creation is on in the form settings, each report becomes a case with the priority, tags and assignees you set. Assign it to the security lead rather than a general queue.

  4. Export CSV for the incident log

    Export CSV from the grid to copy the intake list into your incident log, and keep each original submission as it was received.

Working checklist

Steps after the report is in

First ten minutes

  • Stop sharing the suspicious message or file with others
  • Do not delete the email, file or message to clean up
  • Write down the time you first noticed it
  • Submit this report, then follow the security team's instructions

Inside the security team

  • Confirm the account or device owner
  • Decide whether access should be reset or suspended
  • Record each action with its time
  • Ask the privacy or legal lead whether any notice duty applies

After closure

  • Write the account of events in plain language
  • Note which control or habit would have caught it earlier
  • Share the lesson with the people who were targeted

Frequently asked questions

What should an IT security incident report include?

The kind of event, when it was first noticed, what was seen, which systems or accounts are involved and what was already done. Leave out the secret or the data itself. The security team can ask for more detail after the first report.

What does a good security incident report example look like?

A good example separates facts from guesses and lists them in the order they happened. The example on this page is fictional and uses no real names, systems or addresses.

How is a cyber security incident report different from an IT incident report?

An IT incident report usually covers outages and failures. A security report covers suspected misuse, compromise or exposure. Use this form for the second group, and send service outages to the system outage notification.

Does a lost laptop need a security incident report?

Yes, when the device may hold company data or give access to company accounts. Report it as soon as it is missing, even if you think it may turn up. The security team decides whether to lock or wipe it.

How to build it
